Need more image sizes for your blog? Here's a plugin (9 posts)

I just released my new plugin, called 'Additional image sizes'. You can download it from here. I'd like to get some feedback to see how I can improve it.

With this plugin, users can add and remove intermediate image sizes. The plugin can also make copies of existing images with these new sizes. Users will be able to use the images in their posts or use them in their theme with the use of the 'Get the image' plugin (this is the use case I had in mind mostly).

Any chance have any guesses why this won't work in wordpress mu? It installs fine, and I can add sizes just fine, and they show up in the add image screen, but when I go to upload, none of the images are uploaded other than thumbnail and full size, and it's not added to the gallery.

Is there a way this could work without 'Get the image' plugin? Ideally, to make it work with wp_get_attachment_image_src( $id, $size ) or at least provide your own function, like get_additional_image( $image, $size )

There's no need to use the Get the image plugin. You can use your own function for retrieving images, use a different plugin or use WP 2.9's built in thumbnail functions. Providing a function for that is beyond the scope of this plugin though.
